Hi, I'm wondering if anyone might have a creative solution to something. My situation is that my YWAM location has DSL internet that allows 4 dynamic IP's. We have a switch connected to our DSL modem that will grab onto an IP per one of its 4 ports. My understanding is that each of those 4 ports (or IP's) should be able to get the published speed of 768Kbps download/128 Kbps upload. Is this correct/possible? If so, here's my question... is there a way to bridge those 4 IP's & combine their summed speeds (specifically on the upload)? My reasoning for this is that our current 128 Kbps upload on one IP address is just too slow to run a GENESIS link over IP. So, I'm looking for a creative way to increase that upload speed without much or any cost increase.
Thanks for your replies!

Answer somewhat revealed....
Mike did some research for me & it turns out that even if I would bond my IP's together, it's not possible to increase upload speed at all.
Sorry for the overlap.

4 ip's is something different than 4 lines
The speed of your DSL is measured in total. The IP's is just about how many computers can be seen from the outside. (I would recommend that to be one btw)
You can compare it with a car. The whole car can go 120 km/h, but has 4 seats. It does not mean that if you fill up the four seats the car can go 480 km/h.

(And are you sure that 128 kbps is too slow? Because ISDN has only 64 kbps. It should be possible too downgrade the stream a bit? But I am not in Genesis so I don';t know :))
Upload requirements GENESIS IP
In reality (with today's equipment) running GENESIS over IP on the public internet should have at least 256kbps down and upstream. The very new gear that supports H264, MPEG4 and QOS can handle lower speeds better but the equipment in Latvia (just 2 years old) is limited to H263 video and has no QOS.
GENESIS sends highly compressed video for full screen projection in full duplex mode. (using industry standard videoconferencing equipment).
Last week we had excellent links between Sweden and Brazil, Switzerland, Colorado Springs and Alaska. All these were 256k and higher on IP. We also had slower links with Ukraine on ISDN and Colombia on IP at 128Kbps. Those were all on H264 compliant gear. Our links with Latvia were less successful with serious video degradation.
I have been amazed at the rapid developments in the videoconference industry and the big difference H.264 makes on slow links. It is like double the video quality in the same space.
